To 17/ I /LO.'It it may concern:

lie it known that l, Josnrn Gnnnowinoni, a subject of A.ustria Hungary, residing; at Detroit, in the county of llfayne and State of li'l ichigap have invented certain new and useful Qinmrovements in Vehisle- Wheels, of which the following is a specifination.

This invention relates to rollers or wheels for car turning jacks or trucks.

Qne object of the invention is to provide a non-swivelinpwheel which is so arranged that it may housed to move a truck in anydirection without dragging and scarring the iioor. i

Another object of the invention is to provide a wheel of this character with means for connecting it swivelly to the track or jack.

With the above and other obJeets in View, as will he hereinafter apparent the invention consists in general of certain novel details oi construction and combinations oi parts hereinafter fully described, illustrated in the accompanying drawing, and spec-1h cally claimed.

In the accompanying drawing, like characters of reference indicate like parts in the several views, and v .l igrure l is a side elevation of the device, the shaft being shown in section.

Fin. 2 is a. detail section on the line 2--2 of Fig. 1.

i ig. Z3 is an edge view of the device partly broken away. 7

Fig. 4 is a vertical median svcl'ion through Fig. 3. I

Fig. 5 is a section on the line of Fig. 4;, a

in carrying out the objects of this invention and in the mbodiinent of the device herein shown there has been disclosed a yoke having double arms \vhirh are connected at their upper ends by means of bearing eves ii. The arms of this yoke 10 are provided wilh suitable openings 12 For the reception of a. shaft 13, On this shaft 13 is mounted the wheel body which conststs ot a pair of circular-plates 14 having Jheir peripheries recessed at intervals as at 15,

Moreover the confronting faces of these plates are provided with grooves adjacent the peripheries and in these grooves are held short shafts l6 \vhereon are mounted rollers 17' the outer portions at which pro joct beyond the peripheries of the disks 14:. The two disks are held together by suitable screw bolts lb and if desired the shai it 13 may be extended to connect a pair of the yokes 10. A suitable pin connection may be made between this device and the body the truck so as to allow for swinging movement oi the yoke as will be readily understood. This pm connection does not form part of the invention and is therefore not particularly illustrated.

In the operation of the device it will he seen that when the jack or the like mecha-- nism supported on this wheel, backward and forward movement may be obtained by rotation of the main wheel comprising the disks 1. while lateral movement is permitted by the roller 17, each movement heing a rolling; movement. it will be obvious that a combination of these two movements may be obtained in any angular relation hy the coaction of the main wheel and rollers.

There has thus been provided a simple and eliicicnt device of the kind described and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction of the invention without departing from the material principles thereof it is not therefore desired to confine the invention to the exact form herein shown and described but it is Wished to include all such as properly come within the scope claimed Having thus described the invention, what is claimed as new is:-

1. In a device of the kind dcscriberh a main. wheel consisting of a pair oi disks provided with registering grooves on their confronting faces adjacent their l'ieripheries, said disks being further provided with regn isterirn recesses extending radially inward from their peripheries, shafts mounted in said grooves rollers rotatably mounted on said shafts and means to'hold the disks together.

2. In a device of the kind described, a yoke provided at its upper and with mwns for pivotal connection to a strucmn'e a shaft extending through Hm owe1' and of said yoke transversely .10 the commuting means at the upper end "thereof, a main Wheel. 0211' ried by said shaft, and rollers arranged. p riphemlly around the 11min Wheel zzmi haw 4 I A 1 111;; the] 1" axes at rlght angles to the was oi the mam Wheel.
